HEEL-FINISHING MACHINE.

eminence roaming part a Letters recent to. 743,994, dated November 10, 1903.

Original application filed March 25, 1902, Serial no. 99,851. Divided and this application filed May 4,1903. Serial No. 155,627. (No model.)

To all whom, it may concern:

Be it known that I, Bonner W. THOMSON, a citizen of the United States, residing at Lynn, in the county of Essex and Commonwealth of 5 Massachusetts, have invented certain Improvements in Heel-Finishing Machines, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the w drawings indicating like parts in the several figures.

The present invention relates to heel-finishing machines for applying wax to the edges of heels by means of a rotary wheel or other :5 work member, and this application is a division from pending application, Serial No. 99,851, filed March 25, 1902.

The object of the invention is to improve the construction and arrangement of ma- 2o chines of this class.

2 5 man whereby the wax-supplying means may.

be moved toward and from position for supplying wax.

Anotherfeature of the invention consists in providing wax-supplying means for delivering wax directly to the work member and other means for heating the work member, together with means under the control of the workman for rendering both said heating and said wax-supplying means inoperative.

3 5 Other features of the invention, including certain details of construction and combinations of parts, will be hereinafter described, and pointed out in the claims.

Figure 1 is a frontele vationpf a machine em bodying my invention in one of the best forms which I have devised. Fig. 2 is a plan view of the machine. Fig. 3 is a sectional view on the line 3 3 of Figs. '1 and 2.

The frame 'A is provided with bearings for a shaft 2, on which are mounted fast and loose pulleys at and 6, adapted to receive a belt 8, by which the shaft may berotated. The work member 10 is mounted on the shaft 2 and is here shown as a flexible non-metallic 5o work-rubbing tool, which may be a cloth wheel'or a cloth-covered wheel or brush of any suitable construction.

The wax-supplying means comprises a waxholder 12, from which the wax is supplied directly to the work member 10. The waxholder is mounted on a movable support 14, which in the embodiment of the invention here shown is a lever fulcrumed on a shaft 16 and acted upon by a spring 18 to hold the wax-holder in operative relation to the work member. Means is provided by which the workman may actuate the support 14 to move the wax-holder into a position where it is inoperative for supplying Wax to the work memher. To this end the arm 20 0f the lever 14 is arranged to be acted upon by the cam-surface 22 of a controlling device 24. The controlling device is shown as a lever pivoted at 26 to the frame A and the free end of which is extended into position to be reached con- 7: veniently by a workman standing in position for presenting the heel of a shoe to the work member 10. This arrangement enables the workman to move the wax-supplying means into an inoperative position when the use of the'machine is to be temporarily discontinued or when for any reason he desires to discontinue the delivery of wax to the work member 10. After the controlling device 24 is moved to place the wax-supplying means in inoperative position it will continue to hold said supplying means'away from the work member until it is reversely moved by the Workman. When it is desired to deliver again. the wax, the controlling device will by movement in the opposite direction release the arm 20 ofthe lever 14 and permit the spring 18 to raise the wax-holder into operative'position.

The wax commonly employed in machines of this class is solid at normal temperatures and requires to be melted in order that it may be used to the best advantage. I have therefore made the wax-holder 12 in the form of a wax-pot and have arranged gas-pipes 28, provided with suitable burners, so that gasfiames may be made to heat the wax-pot and melt the wax.

I prefer to employ as a part of the wax-supplying means a roll or disk 30, arranged to dip mo into the wax in the wax-pot and by running in contact with the rim of the work member when the wax-supplying means is in operative position deliver the wax to the work member. The wax-delivering disk may be conveniently mounted in hearings in the waxpot and may be rotated by frictional contact with the positivelyrotated work member. The delivering device might of course be rotated by means independent of the work member, if so desired. It is obvious that the delivering device will become heated by run ning in the hot wax, and as it might injure the work member if allowed to remain in contact with said work member atsuch times as the latter is standing idle it is very advantageous to equip the machine with means by which the workman may move the wax-supplying means at will, as above described, into an inoperative position, such that the delivering device is out of contact with the work member.

The disk of the wax-supplying means delivers the wax in a thin line on the work member, and it is desirable that the Wax be spread over the working face of said member in order that it may be applied evenly to the work. I have therefore provided means (shown as a roll arranged to act on the work member to spread the wax between the point where the wax is applied to it and the point where it engages the work.

It is found that to obtain the best results in finishing heels with the wax commonly used for the purpose the wax should be applied to the heel in as hot a condition as is practicable. I have therefore equipped the machine with means for heating the Work member so as to maintain the wax hot while it is being rubbed onto the heel. To this end in the embodiment of the invention herein shown I have provided means for heating the roll 40, which by running in contact with the work member will heat the working face of said member without burning or otherwise injuring it. The roll as here shown is provided with a wide rim shaped in counterpart of the rim of the Work member and also with a relatively thin web 44, connecting said rim to the hub and providing a space at the ends of the roll to receive gas-flames from burners of the gas-pipes 28. It is of course obvious that the means for heating the work member might be constructed and used independently of the means for spreading the wax on the surface of the work member. The heated roll 40 is preferably rotated by its frictional contact with the work member; butit might be rotated by independent means, if preferred.

It is desirable to discontinue the heating of the work member when the machine is not in use, so as to avoid the possibility of injuring the work-rubbing surface of the work member, and in order to do this conveniently the machine is equipped with means by which the heated roll may be moved out of operative relation to the work member. The roll is mounted in bearings in arms 46 of the shaft 16, before mentioned, which is a rock-shaft provided with another arm 48 in position to be engaged by a cam-face 50 on the controlling device 24, before described, which may be actuated in one direction for turning the rock-shaft to move the heated roll away from the work member. When the controlling device is moved in the opposite direction, the cam-face 5O permits the heated roll to return by gravity into engagement with the work member. By means of this construction the workman may move the heated roll intoaposition remote from the work member, as shown by dotted lines in Fig. 3, at the same time that he moves the wax-supplying means into its inoperative position, also shown by dotted lines in Fig. 3. The workman is thus enabled to avoid the danger of'the work member being injured by heat from either the roll 40 or from the disk 30 of the wax-supplying means.

The controlling device 24 may be provided also with means, such as the arm 52, by which it is adapted to embrace the belt 8 and to shift the belt from the fast pulley 4 onto the loose pulley 6 at the same time that the heated roll and wax-supplying means are moved into their inoperative positions and to shift the belt in the opposite direction when the said parts are moved into their operative positions. In the operation of the machine the shoe will be held in the hands of the workman and presented to the machine with the edge of the heel against the work member 10. It will be understood that the wax-delivering device 30 and the heated roll 40 are so located as to be out of contact with the work being operated upon by the work member.

Having thus described my invention, I claim as new and desire to secure by Letters Patent of the United States 1. In a machine of the class described, a work member for applying wax to the surface of the work and means for heating said work member, in combination with means independent of said heating means for supplying wax directly to the work member, and means under the control of the workman for moving the heating means and the wax-supplying means toward and from operative relation to the work member.
